Document Contents
This manual covers the complete service documentation for the 1971-1977 Suzuki GT750 water-cooled, two-stroke, three-cylinder engine featuring piston-type valve construction. Diagnostic procedures are covered for troubled starting conditions, power loss scenarios, rough idling, misfiring at acceleration, and engine noise tracing through systematic investigation methods. Wiring diagrams are provided for the 12-volt electrical system architecture, including starter motor circuits, alternator field coil connections, contact breaker assembly configuration, and ignition coil primary/secondary winding arrangements. Fuel system procedures are documented for carburetor VM32SC models with pilot jet, main jet, and float chamber adjustment points across three synchronized units. Adjustment procedures are detailed for engine tune-up including ignition timing calibration using timing gauge technology, spark plug gap specification (0.7-0.8 mm standard), contact point clearance (0.35 mm maximum opening), carburetor throttle valve synchronization, oil pump lever positioning, and clutch cable play establishment.
The manual documents torque specifications for crankcase assembly bolts to ensure proper structural integrity and seal effectiveness.
Featuring a modular arrangement of essential service information, the structure encompasses general specifications with performance curves, engine description detailing aluminum cylinder block construction and three-carburetor fuel delivery, component removal sequences with special tool identification, systematic disassembly procedures, comprehensive inspection methodologies using precision measurement techniques, repair specifications including cylinder honing tolerances and bearing clearance limits, and reassembly protocols with thread lock cement application requirements. Included are specifications for the water pump centrifugal impeller (six-blade, 60-liter-per-minute capacity), radiator aluminum fin-tube construction with pressure relief valve data, SRIS (SUZUKI Recycle Injection System) piping configuration for crankcase oil recirculation, cooling system flushing procedures with anti-freeze mixture ratios, transmission oil capacity documentation (2,200 cc standard, 2,500 cc with overhaul), starter clutch roller mechanism operation, and electrical charging system performance curves at various engine RPM ranges.
